To aZZ whom it may concern:

Be it known that I, HERMAN Q. PRIEBE, citizen of the Un ted States,residing at Blue, Island, in the county oftCook and,

5 State of Illinois, have invented a certain new and useful Improvementin- Truck Frames, of which the following is a full, clear, concise, andexact description.

My-invent-ion relates-to trucks for rail way cars, one object oftheinvention being to provide an improved form of bolster column and animproved means of assembling the same with the balance of the frame. Incarrying out this feature'of my invention I desirably employ two bolstercolumns in each truck side frame, these bolster. coluinns being spacedapart to receive tlre.

in the adjacent arch. bars and there is a re- 1 tainer for furthersecuring the lower'end of each bolster column in assembly wlth thebalance of the frame, these retainers belng riveted or otherwise secured:to' the spring plank that is interposed therebet-ween- The inventionalso has forits object the provision of an improved assembly of thejournal boxes with the side frame... In carrying out this feature of myinvention Tem- 53 upper arch bar and the tie barand being in clamplngrelation to the ad acent journal boxes. A single plate is also employedgagement, this single 1 plate replacing the individual nuts that arecustomarily em-' ployed and co-acting with .bothbolts to prevent theloosening of either. I

scribed in, connection with the accompanying drawings showing thepreferred embodiment thereof and in which Fig. 1 is, aside view,partially in section,,of a-truck constructed in accordance with theinvention; v Fig. 2 is a-sectional plan view on line 2-2 of Fig. 1; Fig.3 is a longitudinal sectional.

view of the central portionof theside-frame showing different relationsassumed bythe of one'o'fthe bolster columns and the re ploy two threadedbolts at each end of the side frame, these bolts passing through thebolster columns in the process of assembling the same with the balanceofthe truck frame; Fig. 4 is alsectional view on line t4 of Fig. 1; Fig. 5is a perspectiveview tainertherefor, in separated relation; and

r Fig. 6 is a perspective view illustrating the threaded-plate employedfor holding one pair of journal boxassembling bolts from turning. V 5 ff 'V-Like parts are indicated by similar characters of referencethroughoutthe different figures.

The truck side frameillustrated includes an upper arch bar orcompressionmembere1,

a lower arch bar 2, and a tie bar 3. In the preferredembodiment of the;invention the bolster 'columnsthat intervene between the arch bars-areformed separately from both ofthe arch bars, though the invention is notto be' thus limited. These'bolster colpreferably formed of; castingswhose upperv ends overhang the upper arch bar-{being suhiciently offsetfor. this purpose. ,The

'umns are illustrated at land 5 and are: 7

overhanging portions of thebolster columns 1 are formed with dependinglpinslfi-whicli are receivablein sockets-7 in the upper arch bar.

Pins 8 are formed upon the lower ends of the bolster columns, beingreceivable with in sockets 9 that are formed in the lower arch bar 2 andthe tie'bar a In order that the bolster columns may perform theirfunction as space preserving and strain transmitting struts they areconstructed to engage the bottom side of the upper archbar and in orderthat the bolster columns may be assembled with the upper arch bar in amanner to afford thisengage mentthereof with the arch bar, the upperendsof the bolster columnsv are formed with inclined ledges. The upperpin (Sand the ledge 10 of each column are spaced apart sufficientlytopermit thev positioning of the p upper 'arch bar between this .pinandledge The invention will be more fully dewhen the bolster column.isinclined ,infthe process of assembly as indicated at .theleft inFig.3.

ends of the bolster columns.

the bolts.

A shoulder 11 is at the top of each lower pin 8 and bears upon the lowerarch bar to co-operate with the corresponding inclined ledge 10 ineffecting engagement between each bolster column and the arch bars.

Any suitable or usual form of spring plank 12 is interposed between thelower Aretainer 13 is employed for fixing the assembly of the lower endof each bolster column with the balance of the truck frame, each bolstercolumn having its lower end between the adjacent outer side of thespring plank 12 and the corresponding retainer which is riveted orotherwise secured to the spring plank. Each retainer has an overhangingportion 14: which rests upon the shoulder 11 and engages the adjacentupright side of the cor responding bolster column whereby movement ofthe lower end of such bolster column vertically or horizontally withrespect to the balance of the truck frame is prevented.

Any suitable type of truck bolster may be employed, the truck bolster15' illustrated being carried upon springs 16 that are bottomed upon thespring plank. Journal boxes 17 are provided at theends of each truckside-frame, each journal box being assembled with its end of the sideframe by means of two bolts 18 which are passed through the convergedendsof the arch bars at the top of the journal box and loosely throughthe tie bar 3. The lower ends of thebolts 18 ofeach box are threaded'andhave threaded engagement with a plate 19 common thereto that underliesthe adjacent end of'the'tiebar. Each journal box is disposed between itsbolts 18 that pass through journal box ears 20. When the bolts arescrewed home the. underlying plate is brought into clamping engagementwith the under side of the, tie bar, this clamping plate co-operatingwith both bolts to prevent either bolt from coming loose. As a furthersafeguard, the bolts pass through pieces of strip metal 21 that areinterposed between the heads of the bolts and the upper arch bar, thesepieces of strip metal being finally brought into Z-form to have theirends engage the heads of the bolts and the upper arch'bar after thebolts have been fully tightened to guard against turning of YVhile thelower arch bar preferably terminates above the journal boxes, theinvention is not to bethus limited.

It will be observed that the bolts 18 also assemble the arch bars andthe tie bar together, these elements all constituting parts of the sideframe and I desire to claim the use of the plate 19 in conjunction withthe bolts when these bolts are employed in this way whether they arealso employed for assembling the journal boxes with the side frame ornot.

lVhile I have hereinshown and particularly described the preferredembodiment of my invention I do not wish to be limited to I the precisedetails of construction shown underside of the'upperarch bar, thebolster column overhanging the upper arch bar, thepin which enters thesocket in the upper arch bar being carried by the overhanging portion ofthe bolster column, the upper pin and inclined ledge being spaced apartsufficiently to permit-the positioning of the upper arch bar between theupper pin and the inclined ledge when the bolster column is-inclined inthe process of assembly.
